Title: Drive connection device for four-wheel drive
Inventor: TSUJITA MITSUHIRO
IPC: F16D31/06
Filed: 1989-05-25
Abstract: PURPOSE:To simplify the construction of a choke means provided on the delivery side of a pump chamber by providing an opening and closing means with a spool, closely fitted in the middle of a connecting hole for connecting the delivery side of the pump chamber to a low pressure portion and slid by receiving hydraulic pressure on one side of it, and for opening and closing the connecting hole according to the slide of the spool. CONSTITUTION:In an opening and closing means 5, the sliding position of a spool 50 is determined by a balance of a hydraulic pressure in a circular groove 24 acting on one side, i.e., the hydraulic pressure on the delivery side of a pump chamber with the energizing force of a coil spring 52 acting on the other side. When the hydraulic pressure is low and a force acting on the spool 50 is lower than the energizing force of the spring 52, a clearance is kept between the mating surfaces of the spool 50 and the stopper 51 and an opening end of an oil feeding hole 50a into an oil tank T is opened. On the other hand, when the hydraulic pressure is higher than the energizing force of a spring 52, the spool 50 is started to slide to the stopper 51 until the disk portion of the spool 50 are made in contact with the cylindrical part end surface of the stopper 51 to suppress the slide movement. Namely, the means 5 serves to open and close a connection hole 47.
